Step-by-step explanation:

Given

[tex]w = 0.3d - 0.5[/tex] [The correct equation]

Required

Find and interpret the 0

To do this, we set [tex]d = 0[/tex]

Substitute 0 for d in [tex]w = 0.3d - 0.5[/tex]

[tex]w = 0.3 * 0 - 0.5[/tex]

[tex]w = 0 - 0.5[/tex]

[tex]w = - 0.5[/tex]

This means that the level of rain is 0.5m below the sea at day 0
